Earlier this week, some members of the Congressional Black Caucus said Biden and Harris would be “a dream ticket,” according to Politico. Lawmakers in the group were still deciding about whether to support Biden or their fellow caucus members in the race for the Democratic presidential nomination: Harris and Sen. Cory Booker of New Jersey.

The nomination battle features more than 20 candidates so far, including several women and people of color who make the field the most diverse ever in a presidential campaign.

Yetearly polls show two white men ― Biden and Sen. Bernie Sanders (I-Vt.) ― consistently in the lead. In HuffPost’s polling in late March, Biden, who had yet to announce his candidacy at the time, was also the only contender whom the majority of Democratic voters (69%) named as capable of beating President Donald Trump next year.

“There has been a lot of conversation by pundits about ‘electability,’” Harris said in a speech in Detroit, suggesting that those omitted from that discussion were people of color and women.

“It leaves out people in this room who helped build cities like Detroit,” said the senator, who is black and Asian, the daughter of immigrants from Jamaica and India. “It leaves out working women who are on their feet all day.”

“The conversation too often suggests certain voters will only vote for certain candidates,” Harris added. “And it is shortsighted, it’s wrong and the voters deserve better.”
